Welcome

When you ride normally, freewheel, brakes, gears, you talk to the bike, you change gear, you brake, you turn. When you ride fixed, the bike talks back to you, the fact that your legs are used to not just raise your speed, but to slow it as well, means you have much more information than you normally would, the bike feeds back more info to you and you are aware of this, get used to it, and then when switching back to your geared/freewheel bike you find it feels unresponsive, you want that immediacy of information that you get from the fixed and you find that your spending more and more time on it.
..., but in the end just keep riding.

When I ride fixed, I brake and turn.
I don't really use my legs for braking, that's what my brake is for
Bob1 is of the road at the moment so I'm riding Bob2 (12 speed).
I ride normally all the time, and yes Bob2 is heavier(and less responsive) than Bob1, but at the moment I'm not missing the (Zen like) immediacy of information.
